Engine/Transmission (1998.5 - 2002) Lift pump again what a POC

[diesel DOG]

Piece of crap POC Sick of lift pumps, leaking roofs, ball joints, dripping oil on the driveway, wires rubbing and shorting under the dash, and transmission problems. This is a ton of problems for one vehicle to have in 70,000 miles. Brakes don't last long either but that is partially my driving. Every time it goes down it seem at the most inopportune time for my business.



Now I have to beg the dealer to fix it fast or pay for it myself What does it cost to have someone do it? I guess 350? I'd do it myself but I will probably mess up my back or knee Thanks!

Pump Cost is $120-150 through Cummins and most shops can change out for Hour or less in labor.

The LP is not really hard to change out yourself. If you do it from above, with out removing the starter it should take about 1/2 hrs if it is your first time. Last one I changed on my truck before my FASS, I change in less than ten minutes. That was LP #4 in 36K! Yeah they are a POS.



Do it yourself and ur saving money.

If you bought the pump yourself, you could have it installed for around $50 and have $200 in it total.

I don't think diesel DOG is complaining about the labor or saving money... he's complaining that they are pieces of crap and always need monitoring and too often, need replacing. Even if the job is "only" $100 or $150 and "only" takes 20 minutes, I can see his point with all the other problems he is listing at only 70,000 miles.



I feel your pain diesel DOG. Some things on these trucks should last longer!

I feel it too. I replaced 4 in 36K! They do suck, (no pun) and it sucks that DC will knowinly use a pump that is out of spec from the pump manufacture ( carter). These pumps are "pusher" type pumps and I think that Carter rates them for no more that 3 feet from the fuel source. My SB/QC is like 6ft to the pump mount from the tank.



Finally got fed up and went aftermarket, with no problems.

If I fix something it is not the end of the world IF it is FIXED. This is a Band-Aid and they have no fix except till they get rid of you when you are out of warranty. Then my Bosch pump will probably go down :--)

I have wondered about this for quite a while, so I guess I'll just ask the question. Do you run your fuel very low before filling up?

I used to maitain pumps at work and I know the worst thing you can do to a DC pump is slug it. That is when it loses the sloshing fuel, revs up and then gets slugged with the returning fuel. It's hell on the bearings and impellers. I have only seen the low fuel light twice since I bought my truck and I filled up soon after. Now I watch closer and fill at about 3/8ths of a tank. I still have the original pump on the truck and it works perfectly at 93,000 miles. In fact I have not spent a penny on repairs or had warranty service. Absolutely nothing has needed repair. The front end is still like new and I replaced the original tires at 89,124 miles. They might have made it to 100,000b but I don't take chances with hydroplaning.

Additionally, it seems as though running the tank down low sends hotter fuel back to the pump. The return fuel has less to mix with and help cool it down in the tank before sending it back to the pump.

 

[diesel DOG]

I try not to but did see the fuel light a few times since 01 I carry 5 or 10 gallons in back for my rough terrain forklifts / Lulls or to dump in the truck. The price of fuel I tend to fill more often it seems cheaper :-laf
